Hi

Both are used for Searching purpose only.

In older versions we used Matchcode

now in newer versions of SAp we use Search helps

See them in SE11 Tcode.

1) Elementary search helps describe a search path. The elementary search help must define where the data of the hit list should be read from (selection method), how the exchange of values between the screen template and selection method is implemented (interface of the search help) and how the online input help should be defined (online behavior of the search help).

2) Collective search helps combine several elementary search helps. A collective search help thus can offer several alternative search paths.

3)An elementary search help defines the standard flow of an input help.

4) A collective search help combines several elementary search helps. The user can thus choose one of several alternative search paths with a collective search help.

5)A collective search help comprises several elementary search helps. It combines all the search paths that are meaningful for a field.

6)Both elementary search helps and other search helps can be included in a collective search help. If other collective search helps are contained in a collective search help, they are expanded to the level of the elementary search helps when the input help is called.

hi,

Both are same

in older versions they are Match codes

and in new versions it is search helps

CREATION:

Go to SE11 Tcode

select search help

give the 'z' search help name and create

select the selection method ur table name eg : 'mara'

dialog module 'display value immediately'.

add the field whatever u want and lpos = 1 and spos = 1 and check import and export parameter.

where left position when displaying and spos = search position

and then save and activate ..

Matchcode:

A matchcode allows you to locate the key of a particular database record (e.g. account number) by entering any field value contained in the record. The system then displays a list of records matching the specifications.matchcode OBJECTS are independent transport objects.the numbers 0 to 9 are reserved for us to create our own Match Code IDs for a SAP defined Matchcode object.

If the data in one of the base tables of a matchcode ID changes, the matchcode data has to be updated. The update type stipulates when the matchcode is to be updated and how it is to be done. The update type also specifies which method is to be used for Building matchcodes . You must specify the update type when you define a matchcode ID.

refer to these:

refer to these thread also

Also,

There is no difference between Search helps and match code objects.

Search helps are the Advanced concept of Match codes.

SAP Converted match codes to Search helps.

Index :

An Index is a copy of database table having few numbers of fields. This copy is always in sorted form. As we know, Sorted data would always have a speed access from a database table. Hence, we use an index for the table while reading the database records. Index also contains a pointer pointing towards actual database table so that it can access fields that are not contained in the Index

Matchcodes were replaced with Search Helps starting with Release 4.0. Please use search helps to assign an input help to a field.

Existing matchcodes were automatically converted to search helps. A matchcode object is hereby converted to a collective search help with the same name. Each matchcode ID of the matchcode object is converted into an elementary search help with the same name and assigned to the collective search help created from the matchcode object.

A matchcode is a means of finding data records stored in the system. The matchcode is defined in the ABAP Dictionary in two steps:

You first define the relevant tables and fields for the search in a matchcode object. A matchcode object describes the set of all possible search paths for a search string.

You then create one or more matchcode IDs for a matchcode object. A matchcode ID describes a special search path for a search string. The matchcode ID defines the fields or field combinations to be used in the search.
